Vehicle description[edit]

Prototypes of this class have rear wheel drive, Volkswagen-based 2-wheel drive, and most feature a 4130 chrome tube-frame chassis covered by a fiberglass, aluminum or other composite body. Single or two seat vehicles are limited to prototype engines with a link-pin front suspension system with IRS trailing arm rear suspensions.

Class requirements[edit]


Engines must utilize VW series type 1, 1600cc, U.S. model sedan components and dimensions. Compression ratio and camshaft duration are unlimited. Stock dual-port cylinder heads cannot be ported or otherwise modified other than by flycutting for compression and 3-angle valve job. 1-piece stainless steel valves are allowed. Valve train is open for valve springs, retainers, locks, pushrods, and lifters; however, stock rocker arms must be utilized and their lift ratio must remain stock 1.1:1. Reciprocating assembly must be stock VW components but may be balanced. In the case of the connecting rods: one rod must remain untouched and the other 3 rods may be balanced to match. Pistons may be interchanged to forged, and engine cases may be machined for compression. Full flow oiling, oil galley plugs, case gussets, shuffle pinning, oil squirters, bronze lifter bores are all common case modifications. A top quality 2-1600 engine will produce approximately 85 hp and withstand 5000-6000 rpm operation during the course of a full length event, sometimes lasting over 25 hours.
